The emperor of the temple "Xuanzong" generally made a difference to make the dynasty prosperous and prosperous. Among the orthodox dynasties of China, there were only four emperors with the temple name Xuanzong, and only two of them, in my opinion, really deserved the word "Xuan".
The first Tang Xuanzong Li Chen. Before and after Tang Xuanzong's succession, the environment was very harsh, with eunuchs monopolizing power inside and feudal towns outside, and Datang was in a dangerous period of internal and external troubles. In order to protect himself from Tang Xuanzong's ascension to the throne, he was considered "unwise (not intelligent)" in the palace.
"The emperor is obscure on the outside and inward, seriously reticent, and has a special vision. When he was young, he thought it was not wise. ”
After ascending the throne, Li Chen was diligent in political affairs and diligently sought governance. He also spent a very short time to remove Li Deyu, a major minister of Emperor Wuzong of Tang, from the temple. During Li Chen's reign, he also corrected the malpractice of exterminating Buddhism that was overcorrected during the Wuzong period, so that it was properly restored. Although Li Chen is lenient and loves people, his usage is extremely strict and strict. Especially for the people around him, Li Chen strictly forbade them to interfere in the politics of the dynasty.
Li Chen is a man of discernment and calmness, from the flow of advice, respectful and frugal, and loves the people. During his reign, he straightened out the administration of officials and restricted the clan and eunuchs, and all the hundred officials who died in the Ganlu Rebellion except Zheng Zhu and Li Xun were exposed. On the external front, he defeated Tubo, recaptured Hehuang, and stabilized The North and Annan. In particular, the reconquest of Hehuang was one of the major military victories of Tang against Tubo after the Anshi Rebellion.
During the reign of Emperor Xuanzong of Tang, the country was relatively stable and prosperous, and history called this period the "rule of the great middle". Therefore, until the fall of the Tang Dynasty, the people still thought about it and called Li Chen "Little Taizong".
Li Chen, following the example of Tang Taizong Li Shimin, ruled the country diligently and frugally, showed compassion for the people, reduced taxes, and paid attention to the selection of talents. Li Chen's large areas of lost land occupied by Tubo after the Reconquest of Anshi made the Tang Dynasty somewhat stronger. The people became increasingly prosperous, so that the already decaying government presented a well-off situation of "Zhongxing". However, Tang Xuanzong's reign was too short, and his successors were faint, and the Tang Dynasty experienced a short period of prosperity and quickly fell into the situation of the division of the feudal towns, and less than 50 years after Xuanzong's death, the Tang Dynasty perished.
The second Jin Xuanzong completed Yan Xun. Jin Xuanzong "has the ambition to make great efforts to govern." Trace his diligent government and worry about the people, and the cause of ZTE can be expected", but he has a suspicious personality, cowardice and incompetence. In 1214, when the Mongol army besieged the city, Jin Xuanzong hurriedly asked the Mongols for peace and began to move the capital. This move of Jin Xuanzong greatly shook people's hearts. The generals of the surrender faction and the Khitan and Han military officials and landlords who were oppressed by Jin rebelled against Jin and surrendered to Mongolia. Genghis Khan learned of Xuanzong's southward flight from the Jin Dynasty generals who had surrendered to Mongolia, and saw clearly the corruption and incompetence of the Jin Dynasty. At the beginning of the third year of Zhenyou (1215), the Mongol army once again attacked the capital of Zhongdu, and in May of the third year of Zhenyou (1215), Zhongyu was attacked by the Mongol army.
After moving the capital, because of the problem of the old coin, regardless of the strong enemy of Mongolia, instead turned around to attack the Southern Song Dynasty, the result was a great defeat of the Jin army, and from then on, the Song Dynasty swept away the "fear of war" and "cowardice" mentality of the Jin soldiers in the past, and the two sides tore their faces, you attacked me and killed, you retreated and attacked, and the "peace" of the Song and Jin completely became the "past tense".
Only 10 years after The Death of Emperor Xuanzong of Jin, the Kingdom of Jin was destroyed by the Mongols. For the demise of the Jin Dynasty, Jin Xuanzong had to bear a great responsibility, and he really could not afford Xuanzong's temple name.
The third Ming Xuanzong Zhu Zhanji. When Zhu Zhanji ascended the throne, the world was basically peaceful, and what should be tossed, Zhu Di had already tossed it in front, and the construction of civil engineering and the large-scale use of troops were all completed by Zhu Di, and he took over an empire that had no internal consumption and no fatal border troubles outside. Moreover, although his father reigned for a short time, many policies that benefited the country and the people had already begun to be implemented, and he only needed Cao to follow Xiao's rules and follow the steps.
At that time, the main problem in China was that Zhu Di had been tossing and turning for many years, the country was already overloaded, and there was a second uncle who was looking at the tiger at any time ready to seize the throne, and the problem of the king of the clan was a time bomb. However, Zhu Zhanji's second uncle rebelled like a disturbance, Zhu Zhanji personally marched, and before he could fight much, he surrendered, and then locked his second uncle into a copper jar and roasted him alive.
During his reign, Zhu Zhanji inherited the cause of his ancestors, appointed a number of sages such as "Sanyang", Jianyi, Xia Yuanji, Yu Qian, Zhang Fu, etc., and exerted great efforts to promote the Ming Dynasty to the Taiping Dynasty, and the eleven years of his and his father's reign were called "the rule of Renxuan" by historians.
However, he made a big mistake during his tenure, in order to balance the power of the increasingly powerful civilian official clique, he increased the power of eunuchs, laying hidden dangers for the future monopoly of eunuchs. In addition, he is keen to tease the clams, so he is known as the "Emperor of the Cockroaches", but the flaws are not hidden. After his death, the Ming Dynasty began to decline.
The fourth was Emperor Xuanzong of the Qing Dynasty, emperor Ai Xinjueluo Minning, also known as the Daoguang Emperor. Daoguang was a diligent and frugal emperor, but he did little. Although he lived frugally and even wore patched clothes, he was slightly limited, and social ills were hard to return. In the twentieth year of Daoguang (1840), the Sino-British Opium War broke out, China was defeated, and was forced to sign the Treaty of Nanking in the twenty-second year of Daoguang (1842), which humiliated the country, and in the following eight years, Min Ning Gou appeased and refused to change, while internal and external troubles became increasingly serious, the Taiping Heavenly Kingdom Movement was already brewing, and the Qing Dynasty was in crisis.
Although he straightened out the administration of officials, straightened out the salt administration, connected shipping, quelled the Zhang Ge rebellion, strictly prohibited opium, practiced frugality, and was diligent in government affairs, he did not stop the downward trend of the Qing Dynasty, and there was a lot of moisture for the temple number of "Xuanzong".
In the entire feudal dynasty, in my opinion, only Tang Xuanzong and Ming Xuanzong are really worthy of "Xuanzong", but it is a pity that the life of these two monarchs who have made a difference is too short. Tang Xuanzong reigned for 13 years, less than 50 years after his death, the Tang Dynasty disappeared; Ming Xuanzong reigned for only 10 years, after his death the young Tianzi succeeded to the throne, the northern conquest of Mongolia, the defeat of Tumu Fort, the emperor was captured, more than 500,000 elite and many noble generals were killed, and the family accumulated by the "Rule of Ren Xuan" was destroyed in a battle.
